I am having similar problem. I entered an amount in "other income not reported on a w-2" and "other miscellaneous income". I am now trying to delete both since the amount was incorrect. I can delete the "other miscellaneous income" but not the "other income not reported on a w-2". I have gone through the process several times to say No, I have not received other income. There is never an option to delete or a trash can symbol. I exited Turbotax and logged in again and went through the process and the incorrect amount is still showing. There is no form associated with it for me to delete as far as I know
